Norgren RM1L-1GD-NAV Miniature Precision Regulator - G1/8
Part Number: RM1L-1GD-NAV
Quick Summary
Miniature precision regulator Norgren RM1L-1GD-NAV delivers precise pressure control for compact pneumatic systems. Many engineers struggle with over-pressurization, pressure drop, and unstable flow in tight spaces. In regulated environments, verify critical certifications such as SIL, CE and IP ratings to ensure safety and reliability, particularly for gas and medical oxygen applications. This device is designed for compressed air and gases across a wide temperature range, offering reliable operation and predictable performance. By aligning the regulator with your existing RM1 ecosystem, you gain installation efficiency and consistent downstream pressure, enabling cost savings and better process stability in high-demand applications.

FAQs
The RM1L-1GD-NAV uses a G1/8 port, so compatible threaded fittings are required for a secure, leak-free connection. Use appropriate thread sealant or tape, verify alignment to avoid cross-threading, and ensure the regulator is mounted with a stable, vibration-free base. Consider upstream filtration and downstream pipework to maintain clean compressed air and gas flow within the -5 to 95 °C range for reliable operation.
The 0–0.35 bar outlet range allows tight, repeatable downstream pressure control, minimizing overshoot and oscillations in sensitive circuits. This is ideal for precision actuation and metering in compact pneumatic assemblies, reducing waste and improving cycle times. For best results, calibrate with a stable upstream supply and monitor downstream pressure under typical load conditions.
Yes, the extended description notes suitability for oxygen service and medical applications. When used in such environments, verify material compatibility (aluminium body, PPS bonnet, FPM elastomers), cleanliness standards, and compliance with applicable regulatory requirements. Always follow medical-grade handling practices and ensure the system meets local medical gas regulations.
The provided data does not specify SIL, CE, or IP certifications. Before procurement, confirm with the supplier whether the RM1L-1GD-NAV carries applicable safety and regulatory marks for your region and application. For medical or hazardous environments, request documentation demonstrating compliance, material certifications, and traceability to support risk assessments.
Expect improved process stability and reduced air/gas waste due to low hysteresis and precise regulation. The aluminium body with PPS bonnet and FPM elastomers supports durability in harsh environments, enabling longer service intervals and lower maintenance costs. Its compact size simplifies installation, potentially reducing downtime and accelerating line productivity.
